What does a solid yellow line on your side of the road indicate?

A solid yellow line on your side of the road signifies that no passing is allowed in that area. This marking is a safety measure indicating that it is unsafe to overtake another vehicle because of potential oncoming traffic or other hazards. The solid line serves to alert drivers that they should remain in their lane and not attempt to cross into incoming traffic, as doing so could result in a dangerous situation such as a head-on collision.

In contrast, a broken yellow line would indicate that passing is permitted under certain conditions, allowing drivers to safely pass when the road is clear. The other options, such as a present hazard warning or road construction ahead, do not specifically pertain to the meaning of a solid yellow line and are instead represented by other road signs or markings.
